/* If JS works, we can add a hidden state via a class, 
   but per rules, default must be visible. 
   We will use IntersectionObserver to add a class that triggers animation 
   only if it hasn't already been seen, or just rely on the transition.
   
   Actually, to strictly follow "content's DEFAULT state must be visible":
   We will use JS to add 'is-visible' which keeps opacity 1.
   Wait, usually reveal animations hide first. 
   Let's do this: The CSS default is visible. 
   We will use JS to add a class 'animate-reveal' that adds a slight fade-in 
   for elements that appear later, but since the default is visible, 
   it will just fade in smoothly.
